To all whom t 77mg/ concern:

Be it known that I, WALTER R. MARTIN, a citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in VVell-Drilling Machines, of which the following is a specification.

Objects of my invention are to provide a well-drilling machine in which the spudding and drilling' devices are readily interchangeable, to provide a novel and improved spudding device, to provide an improved device for adjusting the brake-band, to provide simple'and effective means for permitting a pinion employed for operating the winding-d rum to be placed in and out of gear, to relieve the band-wheel from undesirable strains, and to provide certain novel combinations and details serving to increase the general efficiency of well-drilling machines.

lin the accompanying' drawings, Figure l represents in side elevation a well-drilling machine embodying my invention, the usual mast or derrick being omitted and a portion of the walking-beam being broken away for convenienceV of illustration. 1n this ligure the spudding device is ready for use, while the drilling device is understood to be inactive. Fig. 2. is a detail section on line 2 2 in Fig. 3. Fig. 3 is a section on line 3 3" in Fig. 2. Fig. 4L is a view similar to Fig. l, but showy ing the drilling device in position for use, the

spudding device being removed. Fig. 5 is a sectional plan of the machine, the section being on a horizontal plane below the walkingbeam in Fig. l, the pitman for the walking'- beam and the engine being omitted for convenience of illustration. Fig. 6 is an enlarged detail illustrating the device for adjusting the brake-band. Fig. 7 is a detail further illustrating the device for adjusting the brakeband. Fig. 8 is an enlarged detail view illustrating means for locking the driving-pinion on its shaft, said view being a section in line 5LL 5'L in Fig. 5. Fig. 9 is adetail produced by a section on a plane indicated by line 9' 9a in Fig. 8.

A indicates a wheel-supported body-frame carrying' at one end an engine or motor B of any suitable construction. The band-wheel 'C is supported upon the body-frame and driven from the engine or motor by abelt C', the engine-pulley for such belt being on the side of the engine opposite the balance-wheel, and therefore not shown.

D refers to a winding-drum employed for paying out and winding up the rope or cable D', to which the drilling-tool is in practice attached, as usual. The winding-drum is operated frorn the band-wheel C in a direction to wind up the rope or cable by power-transmitting gearing' comprising a transversely-arranged rotary shaft l, having at one end a friction-wheel 2 engaging the band-wheel C and having upon its opposite end portion a pinion E engaging' a gear 3, which is secured upon an extended journal or axle portion of the winding-drum D.

The pinion E is splined upon the transverse shaft l by a spline 4, Figs. 8 and 9, so as to rotate with such shaft, its connection therewith permitting it to slide longitudinally alongl the shaft fromits position shown in full lines to the position indicated by dotted lines in Fig. 9. Then this pinion is in the position thus illustrated in full lines, it is in engagement with the gear 3, Fig. 5, and when in the position indicated by dotted lines it is out of engagement with said gear.

The pinion E is alternately locked in one and the other of these two positions by aspring locking device F', which, as shown, comprises a locking' rod or pin 5, which is normally projected in one or the other of a couple of sockets 6 and 7 in the splined portion of shaft 1. The rod 5 passes loosely through a bushing 8 in one end of a socket in the hub end of pinion E, and a spring 9 is arranged within said socket and conlined between the inner end of the bushing 8 and a stop 10, which is rigid with the rod 5. 1With this arrangement the pinion E can be positively locked on the rotary shaft 1 in the position shown in Fig. 5 when it is desired to operate the windingdrum in a direction to wind the rope or cable thereon, and when it is desired to permit the drum to run loose, so as to pay out the rope or cable, the operator can readily unlock the pinion and shift it toward the end of the shaft 1, where it will positively lock by reason of latch or pin 5 engagingin the socliet'. (Shown in Fig'. 9.) During the operation of drilling the pinion is locked in this outer position away from the gear 3, as in dotted lines in Fig. 9, and the operation of the winding-drum is controlled by a manually-operated brake- IOO IOS

band F, the shift of the pinion into the 'posis tion shown in Fig. 5 being' made when, for example, it is desired to raise the drill from the well. By thus shifting and locking the pinion upon the shaft the use of a clutch and lever is avoided and the pinion is positively held in engagement with the shaft Without liability of accidental displacement.

The brake-band F is applied to a brake-pulley ll-such, for example, as an untoothed end portion of the gear 3. One end of the brake-band is adjustably connected with a lixture or bracket 12 (see particularly Figs. 6 and 7) on the main frame by one or more bolts or rods 13, fastened to the belt and having threaded end portions extended through holes in the bracket 12 and provided with nuts 14, Fig. 7, which are adjustable thereon for the purpose of adjusting the belts or rods through the bracket. The other end of the brake-band connects with a crank-lever 15, which is operated by the attendant for the purpose of controlling the winding-drum when the driving-power is disconnected from the latter. In order to adjust the brake-band with reference to conditions rendering adjustment desirable, the brake-band can be readily adjusted by simply turning a nut when one rod 13 is used or a couple of nuts when two of such rods are employed without removing the band and without detaching or removing' any connections with such band.

The band-wheel C is secured upon one end of a rotary shaft G, supported upon and extending transversely across the main or body frame A and having upon its opposite end a crank-arm H, which is used for operating the spudding and drilling` devices in alternation.

The spudding device comprises a vibratory lever I, pivoted over the body-frame, and an idler-sheave K for engaging the rope or cable D', which when actuated bythe vibratory spudding device is operated from crank-arm H by a pitman L, adapted for connection with and disconnection from such crank-arm. In order to vary the throw of the pitman, so as to vary the extent of up-and-down movement on the part of the drilling-tool when the spudding device is connected with and operated by the crank-arm, the connection of the pitman with the crank-arm is adjustable in directions toward and away from the axis of theshaft G. As shown, the crank-arm has a series of holes 16, in any one of which the pin or belt connecting' the pitman and crank-arm can be temporarily fixed, thereby providing the crank-arm with an adjustable wrist-pin, which can be adjusted forthe purpose of varying the stroke.

The sheave is supported upon a vibratory lever I by a bearing 17, arranged to straddle the sheave and sustain its journals, and as the rope or cable D passes under the sheave it 'can be removed therefrom when it is not to be operated by the spudding device. To cause the spudding device to work evenly, the lever I is in the nature of a yoke or bail, having its arms 18 and 19 spread apart and hinged or pivoted to bearings such as angle-plates on the body frame, thearm 18 being pivoted, as indicated by dotted lines at 20, and the arm 19 being pivoted, as at 21, Fig. 5, said pivoted points being shown forward of the winding-drum, so that the lever I extends rearwardly.

Then the machine is used for spudding, as in Fig. 1, the rope or cable D passes from the windingdrum forwardly to and about a sheave 22 at the forward end portion of the machine, thence back to and under the sheave K of the spudding device, and thence upwardly to and on a sheave or pulley at the upper portion of any suitable mast or derrick, and thence downwardly so as to suspend the drilling-tool. Illustration of the mast 'or derrick is omitted for the reason that such devices are common and well known in well-drilling machines.

The drilling device comprises a walkingbeam M, supported upon a standard N and provided with a pitman O. The pitman O is adapted for adjustable connection with the crank-arm H when the pitmanL of the spudding device is detached from such crank-arm. After detaching the pitman L from the crankarm H the spudding device can be swung forwardly and folded up out of the way, or it can be detached or removed from the machine. When the spudding device is in use, the detached pitman O can be swung back out of the way and, for example, caused to rest upon one of the rear wheels, as in Fig. 1. I/Vhen the spudding device is placed out of use, the pitman O of the drilling device can be swung forward and attached to the crank H, the rope or cable D being then allowed to pass from pulley 22 directly up to the overhead pulley 'on the mast or derrick and to then drop and engage with a temper-screw or the like on the forward end of the walking-beam M, it being understood that the forward end portion of the walking-beam is shown broken away for convenience of illustration and that when the rope or cable is used in connection with the walking-beam fordrilling it may be connected therewith by any known or suitable device for such purpose. The drilling and spudding devices are therefore readily interchangeable in application to the power-driven crank, and with the arrangement shown the machine is rendered compact and comparatively simple in construction. The rear end of the walking-beam is over the crank H, so that by swinging its pitman O forward proper connection between such pitman and the crank can be made. The pitman O swings rearwardly to remove it from the crank, and the pitman L swings forwardly for a like purpose. The lever I extends overthe windingdrum and has the ends of its arms pivoted for- Ward of such drum. The band-wheel C is also used for operating the sand-reel P, the latter being driven from the former by a friction wheel 23 (shown in dotted lines) and fixed upon one of the journals 24, Fig. 5, of the sand-reel, the effect being that the sandreel is formed or provided with a frictionpulley which engages the inner circumference of the rim of the band-wheel. As the driving-belt C extends forwardly from the bandwheel to the engine, the friction-wheel 23 is arranged in opposition to the tension of the driving-belt on the band-wheel, and to such end the axis of the friction-wheel 23 is in rear of the axis of the band-wheel, while the two leaves of the driving-belt C extend forwardly from the axis of the band-wheel.

It will be seen that in this machine the walking-beam is pivotally supported forward of the band-wheel shaft Gr and at the forward end portion of the body-frame, whereby its rear portion, which extends back from a standard N, overhangs a winding-drum and a portion of the body-frame and terminates substantially at a point over the axis of the shaft Gr. The spudding-lever is also pivoted at the forward end of the machine and extends from its pivotal support upwardly and rearwardly, whereby its rear end is permitted to have a pendent pitman adapted for connection with a crank-shaft on the body-frame. The axis about which the spudding-lever vibrates is in the vicinity of the idler-sheave 22, and it will be observed that this idler-sheave, which is arranged forward of the winding-drum, is substantially elevated to permit the drill rope or cable passing from such sheave 22 back to the sheave on the spudding-lever to lie in a'merely or substantially horizontal line, as illustrated -in Fig. 1, in which the spudding-lever is below the limit of its upstroke. By this arrangement the swing of the spudding-lever in a downward direction causes only a comparative slight increase in length on the part of the rope or cable portion between the two sheaves, and when, therefore, the spudding-lever rises the sudden paying out of rope over and from the spudding-sheave will be avoided. and thereby the rope will be saved from what is commonly termed burning.
